Start with caramelizing the onion.Slice it up finely and heat olive oil in a pan at medium heat. I use 6 of 9.Add onions and a pinch of salt. Fry slowly until golden and soft. It takes about 15-20 minutes, but is well worth that wait.

Fold the meat into a burger shaped circle. You wanna cook it like this, not in a stack that gets to compact ;) ​Slice the jalapeños and add it to the meat with smoked sea salt and ground pepper.

Heat a pan with olive oil. Use high heat. Place the meat in the pan and add cheese on top. Cover with a lid. Cook until the cheese is melted. It goes quite quick, so keep watching.​Toast burger buns in oven.

Plate the dish with chili mayo on the bottom bun. Then caramelized onions and the meat. Finish with propper American mustard and enjoy:)
